[THG]Intel 925XE + P4EE 3.46測試報告
即使Intel把FSB拉到1066搭配高速DDR2仍然很難應付Athlon64.
 http://www.tomshardware.com/cpu/20041101/index.html Conclusion These motherboards, which are close to their final revisions, score clearly better results than the pre-release benchmark results we published a couple of weeks ago. This is especially true of the Asus P5AD2-E, which was able to make the FSB1066 feature into a real advantage in our test labs. Other manufacturers are still fine-tuning their motherboards, aiming to deliver final products before Christmas. However, the battle for more performance has clearly lost its velocity. Despite being a bit faster, the new P4 Extreme Edition is not able to achieve a significant difference in performance over preceding models. In terms of CPU clock speeds, Intel has admittedly hit a ceiling with the Prescott core. That also applies to the 130 nm Gallatin core, as squeezing out higher clock speeds would likely be hard to accomplish without jeopardizing yield rates. Therefore, the balance of power between AMD and Intel remains unchanged: when it comes to gaming, Intel has nothing to thwart the dominance of the Athlon64 family in general, and the FX in particular. On the other hand, audio/video encoding tasks and synthetic benchmarks are usually dominated by Intel processors. The three-level cache architecture of the Extreme Edition processors likely does not benefit very much from the faster FSB speed. The reason is that this design is meant to allow CPU performance to be more independent from memory performance. Everyone interested in buying an Intel system should now insist on the 925XE chipset. It is the same price as the FSB800 part 925X, and both the 915P and 925X could turn out to be a dead-end when it comes to future processor upgrades. Finally, we need to comment on the $999 price point that has been common for Intel's Extreme Edition processors. We must emphasize that the performance increase of the EE relative to an ordinary processor is far too little to justify spending that much money on a CPU. |

話說回來,要壓縮機又要P4EE...在配上DDR2...不如買FX55不是更好,也不用超.....

這種組合了吧..
太貴了...- - AMD的C/P值還比較好... |

Anandtech的也出了, 評論更悲觀.
http://www.anandtech.com/cpuchipset...doc.aspx?i=2261 Final Words So there you have it folks - the 1066MHz FSB does absolutely nothing for performance. The 3.46EE does manage to outperform its 3.4GHz/800MHz FSB predecessor, but the margin of improvement is negligible. Intel desperately needs a win here and other than the more affordable price of the Pentium 4 560, there's very little going for the CPU king these days. It will take higher speed Prescott CPUs or dual core in order for the added bandwidth of the 1066MHz FSB to truly be of any use - and it will take lower latency DDR2 memory to finally give the latest Pentium 4 platforms lower latency memory access than the ones they replaced. We can only wonder what Intel is thinking, releasing an entirely new chipset just four months after they released the original. Granted with very few 925X designs on the market right now, there shouldn't be too many upset 925X owners, but it's still a very strange situation. Either the 1066MHz FSB is going to make its way to CPUs faster than we have anticipated, or Intel has just introduced the world's first useless FSB improvement for the next 9 months. The move to the 1066MHz FSB is in sharp contrast to the past two FSB bumps that we've seen from Intel. The introduction of the 533MHz FSB back in 2002 yielded up to a 12% gain in gaming performance, and a 3 - 6% gain in individual applications as it was paired with PC1066 RDRAM. Then came the 800MHz migration that showed a 3 - 9% increase in gaming performance, and just under a 12% increase in professional application performance. But with the move to the 1066MHz FSB we have a platform launch that, in the spirit of the 925X and 915 launches, does virtually nothing for performance. Is it worth it? Sure, 1066 will be worth it when there are higher clock speed (or dual core) processors to take advantage of it. But given that Intel isn't planning on ramping clock speed up too high anytime soon, we'd say that the 1066MHz FSB is best left for late next year, when more useful implementations of it will appear. |

用壓縮機把FX-55超上3G還是會把P4EE 4G打死  |

感覺只因把時脈拉高 , 比P4 3.4EE快些記憶體效能
要看P4 3.7EE才會有些進步吧 |

FX55要上3G不用壓縮機啦,這會污辱FX55耶....只要小加壓就可以囉~~~
